Highly stable fiber Bragg gratings written in hydrogen-loaded fiber

We demonstrated that the thermal stability of fiber Bragg gratings written in hydrogen-loaded standard fibers can be significantly enhanced by preirradiating the fiber with UV beam before writing gratings. Our experimental result shows that these gratings maintained more than 60% of their initial index modulation after 10 hours at 605/spl deg/C.
